Specification of Letters Patent.

Patented June 26, 1917..

Application filed February 3, 1917. Serial No. 146,424.

To all whom it may concern:

Be it known that I, ERNST WV; Sor-rusrnn, a citizen of the United States, resident of Chicago, in the county of Cook and State of Illinois, have made a certain new and useful Invention in Steam-Motors; and I de clare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a side view of theinvention, partly in section on the line 1l, Fig. 2.

Fig. 2 is a plan View of the inventlon partly in section on the line 2-2, Fig. 1.

The invention has relation to steam motors or engines, having for its object to provide an improved rotary motor which w1ll utilize the waste or exhaust steam and pro vide a maximum power for a minimum expenditure of steam and fuel.

The invention consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the numeral 2 designates a boiler or drum having suitable means for converting the water contained therein into steam, said means consisting preferably of wires 3, surrounding the boiler in the shell thereof and heated by an electric battery 1, said drum being suitably insulated, as by asbestos layer 5 and vacuum space 6.

7 is the motor, consisting of a rotary wheel mounted upon a shaft 8, said wheel running within an outer stationary casing or cylinder 9, provided with end heads 10, 10, bolted thereto at 11. The motor wheel is provided in its circumferential portion with a plurality of radial blades 12, having intervening radial spaces 13, and tightener 'or packingrings 14 are provided at the ends of the easing, at the corners between the end heads and the cylinder.

Mounted upon the outside of the stationary cylinder are longitudinal pipes 15, 16, 17, 18 and 19, usually five in'number, equally spaced apart from each other around the cylinder, the bores of said pipes forming chambers 15, 16', 17 18' and 19', to which the steam is delivered, and communicating respectively with said chambers, and delivering the steam to the blades of the motor wheel, are a plurality of pipes or conduits 20, 21,22, 23 and 24, there being one series of said conduits for each of the steam chamfirst steam chamber 15, and through the delivery conduits 20, the steam impinging against the radial blades of the motor wheel within the spaces between the blades, and usually at about right-angles or a little more than right-angles to said blades. The steam will be delivered in jets from the first series of conduits to the radial blades, and will thereby cause the wheel to rotate to a definite degree, the blades' 'coming consecutively into register with the delivery conduits, and the steam delivered to the blades being, as the blades pass out of register with the conduits, confined within the radial spaces, Which are closed at the bottom and sides and open at their outer ends.

The wheel being rotated as stated, the radial spaces, with the steam confined therein at high pressure, will next come into register with pipes 26, and be thereby conveyed outwardly to the next or second steam eham ber 16, from which the steam will be delivered, through pipes 21, to the wheel blades in the same way as first stated, except that in this case the expansive force of the steam under high pressure is relied upon for the forcible action of the steam upon said blades, there. being no communlcation of the steam chamber 16 w1th the steam drum of the boiler.

The wheel will in this way be caused to rotate further to a definite degree, the steam,

still under high pressure, somewhat reduced,

being confined within the radial spaces, which Wlll. next come mto register with the pipes 27, and'be thereby conveyed outwardly to the steam chamber 17, next in order, from which the steam will be delivered as stated again to the radial blades through pipes 22,: to cause the wheel to rotate further. This operation being continued, the steam will be delivered in turn to the steam chambers 18 and 19, through pipes 28 and 29, and from said chambers, through delivery conduits 23 and 24, to the radial blades in the same way as stated for the delivery to said blades from the pipes 27. In this mam ner the steam will be delivered intermittently from the steam drum to the radial blades at one portion of the wheel, and simultaneously and also intermittently to the radial blades at different locations entirely around the motor wheel, which will thereby be effectually and powerfully rotated.

From the radial spaces last in order the steam is delivered through pipe 30 to the radial blades 31 of an auxiliary motor wheel 32, operating a pump 32 or other suitable engine and having a stationary casing 38, serving to confine the steam Within the radial spaces betiveen said blades, as the blades pass out of register with the delivery endof the pipe 30, the confined steam, under reduced pressure, being delivered successively from said radial spaces to a pipe 35 leading to a feed Water tank 36, said tank having a discharge pipe 37 to the boiler.

' The steam pressure is utilized fully before the steam is discharged into the feed water tank, and Will effectually and powerfully rotate the Inotor'ivith a minimum expendr tui'e of steam and fuel. The auxiliary motor may be used or not, as desired, and the number of steam chambers and of the delivery conduits leading therefrom maybe varied he found best, the number of these conduits being preferably gradually increased from the first steam chamber to the last steam chamber, and the size or cross-sectional area the steam chambers 15, 1G, 17, 1 8 and 19' and of the pipes 26, 27, 28, 29 and 30 being gradually increased in the order stated, in order to accommodate the enlarged volume of the expanding steam.

For the same reason the auxiliary motor wheel 32 is made of considerably greater length than that of the main motor wheel, the radial steam spaces 34 being of correspondingly greater length.

A'Water gage 39 will be usually employed forthe boiler, as. also a safety valve 40 and a steam gage all for the steam drum.

I claim:

1. In a steam motor, a rotary wheel having in its circumferential portion radial blades and intervening radial spaces, a casingclosing said spaces upon the outside, pipes locatedat different points around the periphery and extending transversely of said wheel, a steam generator having communication with/both ends, of the first of said pipes, the balance of said pipes having communication at both ends thereof ivith said radial spaces at different points around the Wheel, and delivery pipes from said transverse pipes to the radial blades at different points around the Wheel.

2. In a steam motor, a rotary Wheel hav ing in its circumferential portion radial blades and intervening radial spaces, a casing closing said spaces upon the outside, pipes located at different points around the periphery and extending transversely of Said wheel, a steam generator having communication with the first of pipes, the balance of said pipes having commiui'ication with said radial spaces at different points around the Wheel, and a plurality of delivery pipes from each of said transverse pipes to the radial blades.
